ERATOPSIS. 1 I 



Subgrnus Eratopsis, Tloernes mil Auinger. 



This group, founded for fossils of the Austrian tertiar}' , will 

 include several recent species. The fii'st and largest species 

 which I refer to it, is also the most doubtful one, for of the 

 many specimens of E. scahriuscula before me, nearly all are 

 smooth and polished, without a trace of a sulcus ; j'et others 

 correspond with the figured examples in the various monographs 

 in having it. 



E. scABRiuscuLA, Gray. PI. 4, fig. 5G. 



Oval, rather narrow, with elevated spire ; ash-pink ; surface 

 smooth and polished, or minutely granulate, with or without an 

 obscure dorsal sulcus. Length, 10 mill. 



W. Coast Central America to Mazatlan. 



E. SULCIFERA, Gray. PI. 4, fig. 51. 



An obscure species, strikingly like the preceding, and said by 

 Gray to come from Cape of Good Hope. Reeve has figured for 

 it a specimen of E. lachryma, Gray, and gives Philippines as 

 locality, whilst the figure in Sowerb3^'s Thesaurus represents an 

 entirely different form, said to occur at Panama. 



E. CORRUGATA, Hinds. PI. 4, fig. 52. 



Minute, white, very finel}^ granulated, sulcus distinct. 

 Length, 4 mill. 



Philippines, 8 fathoms, sandy mud (Cuming) ; 



Port Jackson, Australia (Angas). 

 E. NANA, Duclos. PI. 4, fig. 53. 



Like E. corrugata, but narrower, with finer granulations. 



Length, 4 mill. 



Bed Sea (Mc Andrew) ; Paumotus (Pease). 



E. ScHMELTZfANA, Crosse. PI. 4, figs. 54, 55. 



Narrower than E. nana; tinged with ash or rose, base of 



aperture red-tipped. Length, 3*5 mill. 



Viti Islands. 



Undetermined and Spurious Species. 

 E. VENTRicosA, Gray. Not figured nor recognized. 

 E. PELLUCiDA, Tenison-Woods. = Marginella. 

 Reeve has preoccupied the specific name in Erato
